By means of the technical solutions provided by the disclosure, the problem presenting in the prior art that modifying the software codes when the corresponding relationship among the transfer units is updated results in the poorer expansibility of the service scheduling system and the lower processing efficiency of the system can be solved.

TECHNICAL FIELD

The disclosure relates to the field of communications, and particularly to a service scheduling system, a service scheduling method, and a control device.

BACKGROUND

A communication system comprises a plurality of service processing devices for processing services; after a certain service processing device has processed the service, it may need to schedule the processed service to other service processing devices for subsequent processing; in the prior art, a service scheduling device is generally adopted to schedule the service.

As shown in FIG. 1, an existing service scheduling system comprises a service scheduling device 11 and at least two service processing devices 12; after the service processing device 12 has processed a service, it sends the service to the service scheduling device 11, wherein the service is a service to be scheduled. The service scheduling device 11 is connected with the service processing devices 12 via a plurality of buses, and ports for connecting the buses on the service scheduling device 11 and the service processing devices 12 are called bus ports.

One bus port comprises a plurality of transfer units, which are in one to one corresponding to transfer units in a connected bus port, so that the corresponding transfer unit can be determined as long as two connected bus ports are determined; for example, a service processing device A is connected with a service scheduling device a via two buses, comprising a bus 1 and a bus 2, wherein a bus port A1 in the service processing device A is connected with a bus port a1 in the service scheduling device a via the bus 1, and a bus port A2 in the service processing device A is connected with a bus port a2 in the service scheduling device a via the bus 2; all of the bus ports A1, A2, a1 and a2 comprise two transfer units respectively, wherein the bus port A1 comprises a transfer unit A11 and a transfer unit A12, the bus port A2 comprises a transfer unit A21 and a transfer unit A22, the bus port a1 comprises a transfer unit a11 and a transfer unit a12, and the bus port a2 comprises a transfer unit a21 and a transfer unit a22, then a corresponding relationship among the transfer units is shown in Table 1:

TABLE 1 Transfer unit A11 Transfer unit a11 Transfer unit A12 Transfer unit a12 Transfer unit A21 Transfer unit a21 Transfer unit A22 Transfer unit a22

that is, the transfer unit A11 in the service processing device A sends the service to be scheduled to the transfer unit a11 in the service scheduling device a via the bus 1, the transfer unit A12 in the service processing device A sends the service to be scheduled to the transfer unit a12 in the service scheduling device a via the bus 1, and the rest may be deduced by analogy.

In addition, a scheduling rule for the service scheduling device to schedule the services can be pre-configured, for example, the following rule is preset:

a service to be scheduled sent by the transfer unit A11 in the bus port A1 of the service processing device A is scheduled to a transfer unit B24 in a bus port B2 of a service processing device B.

If the service scheduling device a receives the service to be scheduled from the transfer unit A11 in the bus port A1 of the service processing device A, it can be seen from the above-mentioned preset scheduling rule that, the service needs to be scheduled to the transfer unit B24 in the bus port B2 of the service processing device B, at the moment, the service scheduling device a needs to send the service to be scheduled to the transfer unit B24, so the service scheduling device a must learn from which transfer unit of the service scheduling device a the service is sent, that is, it needs to determine the transfer unit corresponding to the transfer unit B24 from all the transfer units of the service scheduling device a; therefore, the service scheduling device a needs to learn the corresponding relationship among the transfer units of the service scheduling device a and the transfer units in the service processing devices, i.e., the corresponding relationship among the transfer units in the service scheduling system.

In the prior art, the corresponding relationship among the transfer units is generally written into software codes of the service scheduling device; when scheduling a service, the service scheduling device can directly search the corresponding relationship for a transfer unit of the service scheduling device to send the service according to the transfer unit to which the service needs to be scheduled, and then the service scheduling device sends the service to the transfer unit to which the service needs to be scheduled based on the searched transfer unit; if a connection status of the bus ports in the service scheduling system is changed, for example service processing devices are added, bus ports of the service processing devices or service scheduling devices are added, connection relationship among bus ports are changed and the like, the corresponding relationship among transfer units stored in the service scheduling devices needs to be updated at the moment, so the software codes of the service scheduling device must be modified, however, it needs to consume many resources to modify the codes due to a large number of software codes stored in the service scheduling device, which results in poorer expansibility of the service scheduling system and lower processing efficiency of the system.

DETAILED DESCRIPTION

The main implementation principle, a specific implementation method and beneficial effects that can be achieved correspondingly by technical solutions of embodiments of the disclosure will be described in detail with reference to the drawings.

FIG. 2 shows a schematic diagram of a structure of a service scheduling system in an embodiment of the disclosure, wherein the service scheduling system comprises a control device 21, a service scheduling device 22 and at least two service processing devices 23, and the service scheduling device 22 is connected with the service processing devices 23 via bus ports, wherein

the service processing device 23 is configured to send the services to be scheduled to the service scheduling device 22, and process the services scheduled by the service scheduling device 22.

It can be seen from the above processing procedure that, in the technical solutions of the embodiments of the disclosure, the control device is added to the service scheduling system, and the control device obtains the connection status information of the bus port in the service scheduling system respectively, updates the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in service processing devices according to the obtained connection status information of the bus port when judging that the changed connection status information is obtained, and sends the updated first corresponding relationship to the service scheduling device to enable the service scheduling device to schedule the services to be scheduled without modifying software codes in the service scheduling device anymore according to the updated first corresponding relationship, so that expansibility of the service scheduling system and processing efficiency of the system are effectively improved.

Based on the service scheduling system as shown in FIG. 2, an embodiment of the disclosure provides a service scheduling method, as shown in FIG. 3; the specific processing procedure is as follows.

Step 31: the control device obtains connection status information of each bus port in the service scheduling system respectively;

wherein the bus port can be in either a working status or an idle status; if the bus port is in the idle status, the connection status information of the bus port comprises information for identifying that the bus port is in the idle status; if the bus port is in the working status, the connection status information of the bus port comprises information for identifying that the bus port is in the working status, and identification information of a bus port connected with the bus port.

For example, if a bus port A3 is in the working status and is connected with a bus port a4, the connection status information of the bus port A3 can be: the bus port being in the working status and connected with the bus port a4; and the connection status information of the bus port a4 is: the bus port being in the working status and connected with the bus port A3.

In an embodiment of the disclosure, the control device can directly detect the connection status information of the bus port in the service scheduling system, or can receive passively, for example, a network manager sends the connection status information of the bus port in the service scheduling system to the control device.

Step 32: the control device judges whether the changed connection status information is obtained in step 31;

if the bus port A3 of the service processing device A is connected with the bus port a4 of the service scheduling device before the control device obtains the connection status information, but the bus port A3 is no longer connected with the bus port a4 and connected with the bus port a3 after the control device obtains the connection status information, then the connection status information of the bus port A3 at the moment is: the bus port being in the working status and connected with the bus port a3, therefore, the connection status information of the bus port A3 is changed, and meanwhile the connection status information of both the bus port a4 and the bus port a3 is changed.

Step 33: if the judging result of step 32 is yes, the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in the service processing devices is updated according to the obtained connection status information of the bus port;

wherein the process that the control device updates the first corresponding relationship can be and not intended to limit the follows:

the control device firstly obtains a second corresponding relationship among the transfer units in the service processing devices and the bus ports in the service scheduling system, determines a third corresponding relationship among the bus ports in the service scheduling system according to the obtained connection status information of the bus ports, and updates the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in the service processing devices according to the second corresponding relationship and the third corresponding relationship.

For example, if the connection status information of the bus port obtained by the control device is: the service processing device A and the service processing device B being connected with the service scheduling device a respectively, the bus ports A1 and A2 of the service processing device A being connected with the bus ports a2 and a3 of the service scheduling device respectively, and the bus ports B1 and B2 of the service processing device B being connected with the bus ports a1 and a4 of the service scheduling device respectively, then the third corresponding relationship among the bus ports in the service scheduling system can be and not intended to limit Table 2.

TABLE 2 Bus port A1 Bus port a2 Bus port A2 Bus port a3 Bus port B1 Bus port a1 Bus port B2 Bus port a4

If the control device needs to determine the corresponding relationship among the transfer units, it also needs to learn the second corresponding relationship among the transfer units in the service processing devices and the bus ports in the service scheduling system, that is, it needs to obtain the corresponding relationship among the transfer units in the service processing device A and the bus ports A1 and A2, and the corresponding relationship among the transfer units in the service processing device B and the bus ports B1 and B2. The corresponding relationship among the transfer units in the service processing device A and the bus ports can be and not intended to limit Table 3.

TABLE 3 Transfer unit A11 Bus port A1 Transfer unit A12 Bus port A1 Transfer unit A21 Bus port A2 Transfer unit A22 Bus port A2

The corresponding relationship among the transfer units in the service processing device B and the bus ports can be and not intended to limit Table 4.

TABLE 4 Transfer unit B11 Bus port B1 Transfer unit B12 Bus port B1 Transfer unit B21 Bus port B2 Transfer unit B22 Bus port B2

According to the corresponding relationships shown in Table 2, Table 3 and Table 4, the control device can firstly determine the corresponding relationship among the bus ports in the service scheduling device and the transfer units in the service processing devices, wherein the corresponding relationship can be and not intended to limit Table 5.

TABLE 5 Bus port a1 Transfer unit B11 Transfer unit B12 Bus port a2 Transfer unit A11 Transfer unit A12 Bus port a3 Transfer unit A21 Transfer unit A22 Bus port a4 Transfer unit B21 Transfer unit B22

Since the corresponding relationship among the transfer units in a bus port of the service scheduling device and the transfer units on a bus port connected with the bus port of the service scheduling device and positioned in the service processing device is fixed, for example, if a bus port C1 is connected with a bus port D2, then a transfer unit C11 in the bus port C1 is consequentially corresponding to a transfer unit D21 in the bus port D2; therefore, the control device can directly determine the first corresponding relationship among the transfer units in the service scheduling device and the transfer units in the service processing devices according to the corresponding relationship shown in Table 5, the determined first corresponding relationship can be taken as the updated first corresponding relationship, and the updated first corresponding relationship can be and not intended to limit Table 6.

TABLE 6 Transfer unit a11 Transfer unit B11 Transfer unit a12 Transfer unit B12 Transfer unit a21 Transfer unit A11 Transfer unit a22 Transfer unit A12 Transfer unit a31 Transfer unit A21 Transfer unit a32 Transfer unit A22 Transfer unit a41 Transfer unit B21 Transfer unit a42 Transfer unit B22

Step 34: the first corresponding relationship updated in step 33 is sent to the service scheduling device in the service scheduling system to indicate the service scheduling device to schedule services according to the updated first corresponding relationship.

As shown in FIG. 4, the procedure that the service scheduling device schedules services according to the received updated first corresponding relationship is as follows.

Step 41: based on each service to be scheduled, determining a transfer unit which receives the service to be scheduled from transfer units of the service scheduling device.

Step 42: according to the transfer unit determined in step 41, searching the updated first corresponding relationship shown in Table 6 for a transfer unit which sends the service to be scheduled.

Step 43: according to the transfer unit searched in step 42, determining a transfer unit which receives the service to be scheduled, i.e., a transfer unit to which the service to be scheduled should be scheduled, based on a preset scheduling rule.

Step 44: according to the transfer unit determined in step 43, searching the updated first corresponding relationship shown in Table 6 for a transfer unit in the above-mentioned service scheduling device, which needs to send the service to be scheduled to the transfer unit determined in step 43.

Step 45: sending the service to be scheduled to the transfer unit determined in step 43 through the transfer unit searched in step 44.

In the embodiment of the disclosure, the control device can further send the determined third corresponding relationship among the bus ports in the service scheduling system to the service processing devices in the service scheduling system, then the service processing device can determine the bus port, which sends the service to be scheduled, in the service scheduling device according to the third corresponding relationship, can further determine the transfer unit, which sends the service to be scheduled, in the service scheduling device; when the service processing device needs to send alarm information to a network side, information of the determined transfer unit can be included in the alarm information.

In addition, in the embodiment of the disclosure, the control device sends the updated first corresponding relationship and the determined third corresponding relationship to the service scheduling device and the service processing devices respectively in the form of a document.

In the embodiment of the disclosure, if a network manager needs to change the connection status of the bus ports in the service scheduling system, the network manager can power off the service scheduling system to obtain the second corresponding relationship among the transfer units in the service processing devices and the bus ports in the service scheduling system, determine the third corresponding relationship among the bus ports in the service scheduling system according to the changed connection status of the bus ports, and then upload the above-mentioned second corresponding relationship and the third corresponding relationship to the control device in the form of a document; after the service scheduling system is powered on, the control device sends the above-mentioned second corresponding relationship and the third corresponding relationship to the service scheduling device, and the service scheduling device determines the updated first corresponding relationship according to the received second corresponding relationship and the third corresponding relationship and schedules services according to the updated first corresponding relationship. Furthermore, the control device can further send the determined third corresponding relationship among the bus ports in the service scheduling system to the service processing devices in the service scheduling system, and the service processing device can determine the bus port of the service scheduling device which sends services according to the received third corresponding relationship.
